MULTIPLE SECTION HOLLOW-WALL CONSTUCTION.

Specification of Letters Patent.

Patented Mar. 25, 1919.

Application filed November 27, 1916. Serial No. 133,719.

To all wlwm z't may Gomera:

Be it known that I, J oHN A. FERGUSON, a citizen of the United States, resilding' at the city and county of Denver and State of Colorado, have invented certain new and useful Improvements in'Multiple Sectional Hollow-Vall Constructions; and I do hereby declare the following' to be a full, clear, and eXact description of theinvention, such as Will enable others skilled in the art to which it appertains toV make and use the same. i

This invention relates to improvements in hollow walls of the type embodying parallelspaced wall body sections, the broad aim of which generally is to provide for maximum strength and desired thickness, with Vertical air ducts throughout the structure, and at the same time to materially reduce the cost of constructionwi'thout sacrificing stability.

As a rule these walls are built up'in horizontal Courses employing concrete building blocks of varying formsoand providing lateral spacing' webs between the wall body sections, all as well understood inl the art.

In constructing' my improved Wall, I also employ such a tvpe of building block but in connection with flat slab elements, although it may be stated at the outset that, in the instant case, I make no claim to the specific formation of the blocks or the slab elements ;ver 88, the advantageous object and primary essence of my invention residing in the combined relation and arrangement of such blocks and slab elements as associated in the production of a novel wall structure tself, resulting from the manner of so setting the block` and slab elements that, in one course, the blocks form the component elements of the outer wall body` section, while the slabs form the component elements of the inside 'wall body section, the blocks and slabs of the outerland inner wall body sections being reversely disposed in transposed relation, as a bodily whole, in alternate courses of the wall.

Other advanta-ges, in more minor details of structure, will appear from the following disclosure, and the particular features of novelty of the improved7 wall structure will be succinctly set forth in the appended claim, but in order to more clearly understand the same reference is had to the accompanying. drawings, forming a part of this application, in. which dra-wings like parts are desig- Vnated by the same reference numerals in the two views, of which- Figure 1, is a perspective view of a corner section of a wall employing the principles of my invention as embodied in a thick wall of multiple' Sections, and

Fig. :2, is a fragmentary plan view of a two-section wall, .the upper course being so terminated as to' olearly show the disposition i of 'the webbed blocks and slabs of one course relatively to the next succeeding courses.

In carrying out the present invention, the blocks and slab elements, respectively, are of appropriate design and dimensions, and while it will be obvious that I need not limit myself to a block of the double-lug type, still this is an expedient and desirable form foi` illustration.

s shown in' the drawings, therefore, the blocks employed, excepting at the Corners, comprise a fiat surfaced base 1 having laterally disposed spacing` webs 2` projecting from one side, the webs being of uniform length or depth. w

The remaining elements vof the wall consist of the fiat or slab elements 3, of the same dimensions as the base of the blocks 1.

lVith these two basic elements the improved wall is built up'as followsz- Referring first to the two-section wall of i F ig. 2, the lower horizontal course of blocks and slabs (at the 'right of the figure) illustrate the slab 'elements 8 as laid in the plane of the outerwall body section, while the fiat surfaced bases of the blocks 1 lie in the plane of the inner Wall body in the same course, and as shown the end faces of'the webs 2 may preferably be slightly spaced from the inner faces of the slab elements 3 to form air passages 4 opening' communication, in the same course, Vbetween the vVertical rows of air ducts 5 of the whole wall.

` In the upper course, shown at the left of the figure, the positions of both the blocks 1 and the slabs 3 have been shifted or completely transposed as bodily sets, so that in this course, the slabs 3 reversely form the V component elements of the inner wall bodyA .sages on the opposite inside face of the Wall.

Thus the elements 1 and 3 are shifted or transposed, in alternate courses, throughout the whole wall structure.

In the multiple construction, shown Vin Fig. 1, there are introduced intermediate block wall sections, between the outer and 'inner wall body sections, to increase the the blocks of the intermediate wall Sections.

being sin'iilarly disposedto the blocks 1 of the outer wall body section, with their webs extending inwardly in the direction of the slab elements of that course.

In the second course, as illustrated, the bases of the blocks 1 are set in the plane of the inner body wall section, while the slabs 3 are located in the outer `wall body section, the said elements having been completely transposed, as heretofore described with reference to Fg. 2. `The bloclrs of the intermediate wall Sections, have not been completely transposed in the Sense of the -blocks and slabs of the inner andV outer wall Sections, but they` have been turned over in a position reversely to that of the lower course, and with their webs now directed in an opposite direction or toward the slab elements in the outer wall section.

In the third, or uppercourse shown, the elements of the outer and inner wall sections Vhave been again completelyV transposed and the intermediate webbed blocks reversed inV position, so that the several parts again assume the positions of the lowermost course.

Thus in every alternate course there is a complete interchange of elements relative to the adjacent upper and lower courses.

It is apparent that the lintermediate block Sections, do not change the essential wall structure, excepting that they 'act as a substantial supporting filler betweenthe outer and inner wall sections proper to Satisfactorily increase the width of the wall as desired, and this in many instances is very desirable, as for example in packing house or analogous structures, wherein a thoroughly heat resisting wall is essential.

'The multiple section wall construction has a further decided advantage in the building of tall structures, requirlng a substant-ially thick lower or base foundation wall,

which may readily be decreased in thickness, in accordance with building regulations, as the building progresses in height, the upper stories being provided for with a. nine inch double wall as in Fig. 2, and this being accomplished, without the employment of revducing elements, other than the same size double-lug blocks and slabs employed 'throughout i The multiple section wall construction also ing one above the other, in vertically alining rows, and being cemented together` by ma layer of mortar as the courses are laid,

thu's interbonding or tying'the wall Sections securelyV to .each other. 1

vlt may be repeated that I lay no claim to provides for 'the air spaces or passages -Ll the specificelements of the wall'as such, nor

to the broad idea of a hollow` sectional wall, other` than encompassed *bythe scope `ofmy invention as set forth in the ensuing claim, but what I do claim as patentably novel,

is i

In hollowV walliconstruction, an inner fand an outer wall, substantia-lly spaced apart, each built V'up .of'rows of plane-surfaced slabs alternating with rows of laterally webbed building blocks of uniformi'dimensions, disposed complementallyof'the 'blocks and slabs of 'the -other`wall;. and oneor more intermediate walls `composed 'wholly jof laterally 'webbed building blocks of congruent dimensions withthose aforesaid, all' of the buildingblocks, in Vall of the walls containing them in any same horizontal course, being laid with thcirwebs projecting inthe same direction, with the -a-dj'acent end faces of the blocks abutting without spacing therebetween, and with'the end faces of their webs terminating on the sameside of the opp'osed surface of a eontiguous wall ;while in alternatecourses the said blocks are reversely'setto provide for :the Vertical alinement and interbonding of complemental webs, substantially as described.

In testimony whereof I aflix my signature.

JOHN A. FERGUSON.
